Jesus promised all Christians suffering. He also promised He will be with us during that suffering, that we can have so much peace that we rejoice in our suffering.
God acts according to His will not ours. He does not will that all people get the same things all the time. We are individuals with individual lives, personalities, circumstances, etc.
Jesus didn’t heal everyone in the kingdom. He performed those miracles He chose to perform so that we might believe that He, the Son of God, had come so that we might have life.
I spent four years praying with every fiber of my being for my husband to be healed from his congestive heart failure.
My husband was healed, totally and completely when he received the Apostolic Pardon then passed into eternal life.
We have to realize that God answers every prayer. Sometimes He says “no”, sometimes “wait” and sometimes “yes” in a way we never expected. Blessed be God.
